While out walking in the one place I let my ex racing greyhound off lead I sometimes meet a lady I know with her dog & we might walk together or have a chat. Her dog is young & constantly chases mine & jumps on his back. Mine doesn't like this (although he does like other dogs) he doesn't do rolling around or whatever this dog is wanting him to do. Mine has started to growl at him to get him off but the other dog takes no notice. The lady says 'let them sort it out themselves' but I feel a bit sorry for mine as he is constantly running to get away from him. What is the etiquette here? If I put mine on lead as soon as I see her will she be offended?
